Have you ever noticed that wounds seem to heal faster after a dip in the sea? Not that strange, really. “Salt has bactericidal effects and will speed up the healing process,” explains Riikka Hoffrén, founder and CEO of Stockholm Saltspa. She is the heart and soul of this alternative health centre, located in the middle of Stockholm’s picturesque Old Town. The main attraction of Stockholm Saltspa is a room covered from floor to ceiling in salt. Customers spend 40 minutes in this room to treat conditions such as allergies, asthma and psoriasis. To maximise the effect, a special generator blows out salt in the air.
